ByteTrack-TensorRT in C++

Installation

Install opencv with sudo apt-get install libopencv-dev (we don't need a higher version of opencv like v3.3+).

Install eigen-3.3.9 [google], [baidu(code:ueq4)].

unzip eigen-3.3.9.zip
cd eigen-3.3.9
mkdir build
cd build
cmake ..
sudo make install

Prepare serialized engine file

Follow the TensorRT Python demo to convert and save the serialized engine file.

Check the 'model_trt.engine' file, which will be automatically saved at the YOLOX_output dir.

Build the demo

You should set the TensorRT path and CUDA path in CMakeLists.txt.

For bytetrack_s model, we set the input frame size 1088 x 608. For bytetrack_m, bytetrack_l, bytetrack_x models, we set the input frame size 1440 x 800. You can modify the INPUT_W and INPUT_H in src/bytetrack.cpp

static const int INPUT_W = 1088;
static const int INPUT_H = 608;

You can first build the demo:

cd <ByteTrack_HOME>/deploy/TensorRT/cpp
mkdir build
cd build
cmake ..
make

Then you can run the demo with 200 FPS:

./bytetrack ../../../../YOLOX_outputs/yolox_s_mix_det/model_trt.engine -i ../../../../videos/palace.mp4

(If you find the output video lose some frames, you can convert the input video by running:

cd <ByteTrack_HOME>
python3 tools/convert_video.py

to generate an appropriate input video for TensorRT C++ demo. )
